Intake Manifold Gaskets: A Service Rundown
Back in the days when most engines had cast iron blocks, heads and manifolds, the intake manifold could be easily sealed with simple and relatively inexpensive die cut fiber-faced metal gaskets (solid or perforated core). Sealer was usually required to ensure a leak-free installation. But in the late 1980s and early 1990s, fuel systems and
Diagnosing Electrical/Electronic Automatic Transmission Failures
Don’t be alarmed if you pull an automatic transmission trouble code when diagnosing a “check engine” warning light! Since the automatic transmission operation has a major effect on grams-per-mile exhaust emissions, you’re going to see the occasional “global” P0700 to P0900-series diagnostic trouble codes (DTCs). The fact is, if you understand basic transmission operating principles,
2014 Top Shop Finalist: M&W Tire

Air Fuel Ratio Sensors vs. Oxygen Sensors
With fuel prices rising, the need for accurate air/fuel mixture monitoring is more important than ever. The engine computer needs to know what the fuel mixture is with a high degree of precision so it can optimize fuel economy as well as emissions. If the information received by the powertrain control module (PCM) from its

Diagnostic Solutions: Modern Spark Plug Diagnostics and the ‘Art and Science’ of Reading Plugs
With the advent of electronic engine management systems, “reading” spark plugs has become something of a lost art. In the days of mechanical carburetors and distributors, the color and texture of the spark plug’s insulator could provide important information about the air/fuel ratio, spark timing and cylinder condition. Back in the day, the desired insulator
